The Valle Cavanata Nature Reserve (Italian: Riserva Naturale della Valle Cavanata) is a 327-hectare (810-acre) protected area situated in the easternmost part of the Grado Lagoon in Grado, Italy. Valle Cavanata was historically a fish farming area created in the 1920s, in the eastern part of the lagoon of Grado, that was embanked and provided with adjustable floodgates and thus transformed into a brackish area for fish farming. The water level in Valle Cavanata can be modified by the sluice gates; they allow the water to flood the area at high tide or let it out at low tide. More information...
